OIL-FEED DEVICE.

Specification of Letters Patent.

Patented. Nov. 13, 1906.

Application filed February 23, 1906. Serial No. 302,525.

To all w/com it may concern:

Be it known that we, HERBERT O. Simon and HENRY E. SPADE, citizens of the United States, residing at Vicksburg, Kalamazoo county, Michigan, have invented certian new and useful Improvements in Oil-Feed Devices, of which the following is a specification.

This invention relates to improvements in oil feed or charge delivering devices.

Our improved oil feed or charge delivering device is particularly designed for use as a lubricator, although it isvery desirable for use as a liquid hydrocarbon device for explosion-engines and the like.

The objects of this invention are, first, to provide an improved feed device of the class described adapted to deliver a number of charges at the same time; second, to provide an improved feed device of the class described adapted to deliver a fixed amount at each charge; third, to provide an improved feed device of the class described in which the amount delivered is under perfect control fourth, to provide an improved feed device of the class described adapted to accomplish the objects stated, which is very simple and economical in structure.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

Figure 1 is an inverted viewof our improved feed mechanism removed from the oil reservoir or receptacle A, the operating mechanism also being omitted. Fig. 2'is a vertical section of our improved oil-feed mechanism, the driving-gear and plungers being shown in full lines.

In the drawings similar letters ofreference refer to similar parts in both views.

. Referring to the drawings, A is the frame,

from which is suspended the oil reservoir or receptacle A. Arranged within the reservoir A is a cylinder B, preferably open at each end and having a longitudinal slit B therethrough. The cylinder B is suspended from the frame A by means of the rods B. On opposite sides of the slit B are outwardlyprojecting perforatedears b. A bolt 1) is arranged through these cars. On this bolt is a tension-spring b. The tension of this spring is adjusted by means of the nut b on the bolt 6.

Arranged withinthe cylinder is a plunger O. The cylinder is provided with discharge ports or openings 0". These dischargeopenings are connected to the parts to be lubricated by the tubes or pipes C; (See Fig. 2.) The plunger 0 is provided with a plurality of cylinder-like charge-pockets c, with passages 0 opening thereinto. These passages are arranged to register with the discharge-passages c in the cylinder B when the plunger is in its upper position.

It is evident that, if desired, the cylinder B might be closed at its lower end and provided with inlet-ports adapted to register with the inlet-ports 0 when the plunger is in its lower position.

The charge-pockets c are provided with plungers O. A plunger-rod D is provided for the plunger 0, the plunger being slidably mounted thereon. The plunger-rod is provided with suitable shoulders, as cl (1. The plunger is frictionally fitted within the cylinder, so that it is moved with an intermittent movement. This friction can be nicely adjusted by the means we have illustrated, although other forms will readily suggest themselves to those skilled in the art to which this invention relates.

On the plunger rod D is a cross-head e, through which the pocket-plungers O are slidably arranged. These plungers are provided with tappets e a, so that the plungers C are intermittently operated. The tappets 6 are preferably threaded upon the plunger, so that they may be adjusted to control the movement of the pocket-plungers, thereby regulating the charge. The plunger D is connected by the rod E to the crankwheel F, secured to the inner end of the shaft F. The shaft F is provided with suitable bearings on the frame A. On the outer end of the shaft F is a gear-wheel F, with which the gear f is arranged to mesh. On the shaft of this gear is a pulley F.

In the operation of the device, the plunger O bein in its lower or initial position, the plunger-rod D first acts upon the pocketplungers C, lifting them up, and thereby opening the pockets. cant into the pockets through the passages c. The shoulder d then engages the plunger O, lifting the same until 'the passages c are opposite or register with the discharge-passages c of the cylinder B. The return movement of the plungerrod D, engaging the tappets e of the pocket-plungers, forces them downwardly in the pockets and ejecting the oil therefrom through the passages o.

The shoulder d on the plunger then engages the plunger O, carrying it downwardly to the This draws the lubri- IIO 7 end ofthe movement, and on the return stroke paratus.

. discharge-passages of the cylinder.

the operation is repeated. The plunger 0 is, as before stated, held under friction, so that it does not move until engaged by the shoulders of the plunger-rod. These shoulders are,

in effect, tappets for moving the same.

We thus accomplish by a simple mechanism the opening of the pockets in the reservoir and the closing of the same opposite the When the pockets are opened, a vacuum is created, so that they are positively filled even though the lubricant be quite heavy or thick. By adjusting the tappets e the amount of the charge is regulated. It is evident that by this simple construction a number of bearings may be lubricated from a single ap- While our improved feed device is particularly designed as a lubricator, it is, as before remarked, desirable for use as a charge device for explosion-engines and the like.

We have illustrated and described our improved feed device in detail on account of its structural simplicity, although we are aware that it is capable of considerable variation in structural details without departing from our invention.
